Background: Balloon mitral valvuloplasty (BMV) has been successfully performed in patients with symptomatic mitral stenosis. In this study, we evaluate the safety, efficacy and outcome of BMV here in Oman. Methods: The immediate and one year clinical and echocardiographic results of 89 consecutive patients (mean age 34 ± 12 years) who underwent BMV for severe mitral stenosis between January 1997 and June 2007 are reported. Results: The procedure was considered successful in 86 (96%) patients. The hemodynamic mean diastolic gradient decreased from 15.4 ± 5.7 mmHg to 3.4 ± 2.9 mmHg (p < 0.0001). The mean left atrial pressure was reduced from 24 ± 7.1 mmHg to 11.6 ± 3.6 mmHg (p < 0.0001).The mean mitral valve area assessed by 2-D echocardiography increased from 0.9 ± 0.22 cm2 to 1.7 ± 0.26 cm2 (p < 0.0001). Three patients (3.3%) developed moderate to severe mitral regurgitation. Two patients expired, one due to severe mitral regurgitation and another due to sepsis unrelated to the procedure. The one year follow up mean mitral valve area was 1.6 ± 0.24 cm2, restenosis rate was 23%; and 90% of patients were in class I - II. Conclusion: The results of this study show that BMV is a safe and effective procedure for symptomatic mitral stenosis in a low volume center with lower complication rates and good clinical improvement.
